Actuator Performances

• Special scotch yoke design that gives an increased torque and the seat break out point.
• Bush steel alloy and Scotch yoke steel alloy: use of steel parts instead of aluminium parts, ensures high wear resistance to the internal mechanism and consequent longer working life.
• Compact design with reduced overall dimension allows an easy handling & minimal air (energy) consumption.Special compound seals and guide on the sliding pistons, ensures self lubrication for life.
• The special double on one sealing rings grants a longer life maintenance free without O-ring sticking and replacement.
• Internal bores are fine lapped and have anodized surface treatment for lower friction and perfect piston sealing and increases the life of the sliding parts.
• Maintenance free for the full actuator working life.
• Standard stainless steel drive shaft protects against the environmental corrosion.
• Shaft anti-blowing system. The driving shaft/lever construction avoids any possible expulsion of the shaft.
• Atex 2014/34/EU for suitability of the equipment intended for the use in Potentially Explosive Atmosphere.
• Actuator Nominal Torque: from 30 Nm to 3840 Nm.

Mounting flange according with DIN/ISO 5211, DIN 3337: F05 - F07 - F10 - F12 - F14 - F16.

NAMUR standard pressure connection.

Rotation angle: 92° (-1°+91°).

Nominal pressure: 5,6 bar; maximum operating pressure 8,4 bar.

The torque is directly proportional to the operating pressure.

For the simple acting (spring return) actuators the reverse torque is performed only by the spring action, and is independent from the operating pressure.

Temperature: from -20°C to +80°C (Special version HT -20°C to +150°C or LT -50°C to +60°C).

Operating media: compress filtered air not necessarily lubricated (for temperature under 0°C use dry air).

In case of lubricated air, use non-detergent oil compatible with NBR rubber.

All the models are available in double acting “GDV” and simple acting “GSV” version.
